Definitions
- the present invention is concerned with an improved method of installing a hydroelectric turbine onto the seabed or the like, and in particular a method which improves the handling of the electrical cable connected between the hydroelectric turbine and an onshore power station to which electricity generated by the turbine is supplied.
- harnessing tidal energy does provide its own challenges, in particular with respect to the installation and maintenance of tidal power generators, for example hydroelectric turbines, which by the very nature of the operation of same must be located in relatively fast flowing tidal currents, and more than likely located on the seabed.
- tidal power generators for example hydroelectric turbines, which by the very nature of the operation of same must be located in relatively fast flowing tidal currents, and more than likely located on the seabed.
- these turbines must be built on a large scale. Essentially however these turbines must deliver power back to shore for eventual supply into the grid.
- the level of electricity generated by the turbines renders working on the electrical systems a hazardous operation, and this is magnified by the location of the turbines under water on the seabed, and in regions of fast flowing tides.
- the electrical cable extending onshore from each turbine must be relatively large and robust.
- the diameter of the cable which may be in the region of 300-500 mm, and given the length of cable involved, the weight of the cable is significant.
- the handling of the cable is therefore both a difficult and time-consuming operation, made even more difficult by the tidal conditions present at the sites where hydroelectric turbines are deployed.
- the cabling is also relatively inflexible and so the mishandling of same can quickly and easily result in kinking/knotting of the cable, thus rendering same permanently damaged and therefore requiring replacement.
- the present invention therefore provides a method of installing a hydroelectric turbine system comprising the steps of:
- the method comprises positioning the system substantially above the deployment site prior to connecting the cable.
- the method comprises lowering the system from a deployment vessel and simultaneously displacing the deployment vessel such as to maintain tension in the cable.
- the deployment vessel comprises a source of propulsion.
- the method comprises the step of positioning an anchor to be upstream of the system during the lowering step; directly or indirectly connecting the system to the anchor; and using the anchor to achieve the displacement of the system during the lowering thereof.
- the method comprises positioning the anchor on the seabed.
- the method comprises the steps of towing the deployment vessel behind a towing vessel; and utilising the towing vessel to achieve the displacement of the deployment vessel.
- the method comprises the step of winching the deployment vessel towards the towing vessel during lowering of the system in order to achieve the displacement of the deployment vessel.
- the method comprises the step of securing the towing vessel to the anchor and pulling the towing vessel towards the anchor to at least partially achieve the displacement of the deployment vessel.
- the deployment vessel or the towing vessel comprises a dynamic positioning vessel.
- the method comprises the step of marking the location of the pre-laid cable with a floatation device.
- the method comprises lowering the system during a running tide.
- the method comprises the step of laterally displacing the system prior to or as part of final positioning of the system at the deployment site.
- hydroelectric turbine system is intended to mean either a hydroelectric turbine mounted on a base, which can be lowered together onto the seabed; the base in isolation from the turbine, which may be lowered to the seabed and the turbine subsequently lowered into position onto the base; or the turbine in isolation from the base, to be lowered onto the previously located base.
- the method of the present invention involves transporting the turbine 10 into a position substantially above a deployment site S on the seabed B where the turbine 10 is to be located during use.
- an electrical cable C Prior to transporting the turbine 10 into position above the deployment site S an electrical cable C is pre-laid on the seabed B.
- the processes involved in laying the cable C from an onshore location, or from some other location, to the deployment site S are well known and will not be described in any detail hereinafter.
- the final stretch of the cable C leading to the deployment site S for example the last 100 meters, is laid substantially in line with the direction of the prevailing tide T.
- a flotation device in the form of a buoy (not shown) or the like is tethered at or adjacent the free end of the cable C and therefore locatable on the surface of the water W once the turbine 10 is brought into position above the deployment site S. It is also envisaged that it may be more practical to attach an umbilical or extension (not shown) onto the end of the cable C, and that the umbilical/extension would then be the portion that gets raised and lowered from the seabed B.
- the cable C may be used to take power directly ashore, or for daisy chaining the turbine 10 to one or more additional turbines (not shown).
- the turbine 10 With the cable C pre-laid to the deployment site S the turbine 10 is, as mentioned above, brought into position substantially above the deployment site S.
- the turbine 10 is carried by a deployment vessel 12 which may be of any suitable form and, in the embodiment illustrated, is in the form of a non-powered barge 12.
- the deployment vessel 12 may however comprise a source of propulsion.
- a towing vessel in the form of a tug 14 is used in order to tow the turbine 10 and barge 12 into position, and in the embodiment illustrated, against the running tide T.
- a simple tow line 16 is connected between the tug 14 and the barge 12, and may be adjusted in length in order to make small corrections to the position of the turbine 10 and barge 12.
- the tug 14 could however be replaced with a dynamic positioning vessel (not shown) which could then utilise GPS in order to accurately maintain a desired position during the installation process.
- the turbine 10 may be releasably connected to the barge 12 by any number of suitable arrangements, and the details of the connection are not material to the method of the invention, and so will not be described in detail hereinafter.
- At least one anchor 18 is installed, in the embodiment illustrated, at a location on the seabed B upstream of the deployment site S with respect to the direction in which the tide T is flowing during the installation.
- the anchor 18 may be of any suitable form, and in the embodiment illustrated is in the form of a simple rock-type anchor 18. However, the type and/or size of anchor 18 may vary depending on the conditions on the seabed B. Again in order to mark the position above the water W of the anchor 18 it is preferable that a tethered buoy (not shown) or similar marker is secured to the anchor 18, and for reasons described hereinafter.
- the tug 14 is connected to the anchor 18 via an anchor line 20. This is achieved simply by retrieving the buoy (not shown) connected to the anchor 18 onto the tug 14 and then suitably securing the anchor line 20 to the tug 14.
- the anchor 18 now allows the tug 14, and therefore the turbine 10 and barge 12, to hold position against the running tide T. It should however be noted at this point, and as will become clear from the following description of the method of installation of the present invention, that the tug 14 may be dispensed with, and in such a scenario the vessel 12 would be connected directly to the anchor 18. This is a possibility regardless of whether the vessel 12 has a source of propulsion or not.
- the free end of the cable C (or umbilical) is recovered to the surface and electrically connected to the turbine 10 in known manner.
- the cable C may be recovered using a conventional winch arrangement provided on the barge 12, or may be achieved by a separate support vessel (not shown).
- the turbine 10 is prepared for lowering to the seabed B.
- the turbine 10 is pre-mounted on a base 22 which will support the turbine 10 on the seabed B during use.
- the base 22 which is used to secure the turbine 10 to the barge 12.
- the turbine 10 and base 22 together define a hydroelectric turbine system It is envisaged that the cable C could be connected to the base 22, with a suitable connection then being provided between the base 22 and the turbine 10.
- the turbine 10 and base 22 are now lowered towards the seabed B.
- This may be achieved by any suitable means, and in the embodiment illustrated a number of support lines 24 are connected between the barge 12 and the base 22.
- the barge 12 is therefore provided with a corresponding number of winches (not shown) which are operable to raise and lower the support lines 24, and therefore raises and lower the base 22 and turbine 10 towards or away from the seabed B.
- the turbine 10 and base 22 are connected in an under slung arrangement to the barge 12 in order to allow the turbine 10 and base 22 to be quicldy and easily lowered away from the barge 12 towards the seabed B. Any other suitable arrangement may however be employed.
- While the turbine 10 is being lowered towards the seabed B it is simultaneously displaced, and in the embodiment illustrated forwardly against the running tide T and towards the anchor 18, such as to maintain tension in the cable C. This is achieved by either pulling the tug 14 forwardly on the anchor 18, or by shortening the tow line 16 between the tug 14 and the barge 12, or a combination of the above-mentioned procedures. However as mentioned above, the tug 14 may be omitted and the barge 12 connected directly to the anchor 18. In this case the line (not shown) connecting the barge 12 to the anchor 18 would be used to pull the barge 12 forward against the tide T. In either scenario, the turbine 10 will be lowered towards the seabed B along an arced path.
- This path ensures that tension is maintained in the electrical cable C connected to the turbine 10 or base 22. This tension ensures that no kinking or knotting of the cable C can occur during the lowering of the turbine 10.
- the turbine 10 Once the turbine 10 is positioned on the seabed Beach of the support lines 24 can be disconnected therefrom and winched back up onto the barge 12. At this point the turbine 10 may begin operation and feeding power onshore via the cable C, or to any other desired location. At this point, the cable C should be in a straight line with respect to the direction of tidal flow T, and under tension in order to prevent any undue movement thereof during operation.
- the tug 14, or preferably dynamic positioning vessel could be used to initially hold the position of the turbine 10 and barge 12 against the tide T while the cable C is connected to the turbine 10. Once lowering of the turbine 10 is commenced the tug 14 could then pull the barge 12 forwardly in order to achieve the above mention arced path of the turbine 10.
- the method of the present invention could be implemented with the tide flowing in the opposite direction to that described and shown with respect to Figures 1 and 2 .
- the towing vessel 14, and anchor 18 if employed, would need to be on the other side of the barge 12 to that shown in Figures 1 and 2 , in order to be able to hold the barge 12 in a substantially fixed position over the deployment site S.
- the tide could be used to effect displacement of the turbine such as to maintain tension in the cable C.
- This could be achieved for example by feeding out and therefore lengthening the towing line 16 and/or anchor line 20, and simply allowing the tide to carry the barge 12, and therefore the turbine 10, with the tide in order to maintain tension in the cable C. Again this arrangement could be effected without the use of the anchor 18.
